题目内容：

选词填空 She knew better than(to turn,turned,turning,going to turn) around or show panic.
感觉这里省略了什么,She knew it is better to do..than to turn...
1,to turn ,以前听过 than 后面加原形的说法,如果这里有原形 turn,
2,这句话的意思可能是She knew better not to turn ...她知道最好不要回头或表现出恐慌.
3,出自描写中东战争的小说 Sowing the Wind,作者Martha Dodd
4,谢谢您回答我的疑问!
